Used the script from
http://freshfoo.com/blog/disqus-import-script
to import my old comments, with a bit of hacking. I had to add to code
to include email addresses that were in my version of the comments
plug-in. It uses the Disqus API library from
http://code.google.com/p/disqus-python-client/
I only had about 70 comments spread over a few folders, but this made
the job pretty easy.
I can make my version of the code available if anyone wants it.
